Remarks. The resurrection of Bracon bipartitus from synonyms of B. variator Nees, 1811 and the established synonymy with B. rozneri and B. variator var. chinensis

RAHMANI et al. / Turk J Zool are based on examination of the types of the four taxa [the holotype of B. bipartitus Wesmael : ♀, “Coll. Wesmael”, “2066”, “Type”, “ Braco bipartitus ♀ mihi dét. C. Wesmael”, “ Holotypus Bracon bipartitus sp. n. Wesm. 1838”, “ Bracon variator var. bipartitus (Ws.) det. Papp J. 2006”, “3.317” (IRSNB); the holotype of B. rozneri Papp : ♀, “Hungaria, Kondorfa, Sáros-Erdö”, “ 1984.VI.25, leg. Rozner I.”, “ Holotypus Bracon (Gl.) rozneri sp. n. Papp 1998 ”, “Hym. Typ. No. 7781 Museum Budapest” (HNHM); the neotype of B. variator Nees : ♀, “Coll. Wesmael”, “ Braco variator N. ♀, dét. C. Wesmael”, “Belgiuque, Bruxelles”, “ Neotypus Bracon variator Nees, 1811 , des. Papp J., 1982” (IRSNB); the holotype of B. variator var. chinensis Fahringer : ♀, “Provins Kiangsu”, “ China, [Gustaf Isak] Kolthoff ”, “juli”, “ Bracon ♀ variator Nees v. chinensis m. det. Dr. Fahringer, Type”, “NHRS- JUST 000000134” (NHRS)].

Diagnosis. Bracon bipartitus differs from B. variator (as well as from other related species) in the following characters:

1. Segments of hind tarsus with thick bristles on ventral sides ( Figure 3f ). Hind tibia and basitarsus somewhat swollen. Head linearly narrowed below eyes (front view;

Figure 3b ). Second metasomal suture medially straight ( Figure 3d ). 2.6–3.6 mm … Bracon bipartitus Wesmael, 1983

– Segments of hind tarsus without thick bristles on ventral sides. Hind tibia and basitarsus not swollen. Head roundly narrowed below eyes (front view). Second metasomal suture medially curved. 2.5–5.0 mm … Bracon variator Nees, 1811
